Which outcome results when a semiconducting crystal experiences quenching?

A)Increased density of crystalline defects
B)Reduced overall free carrier mobility
C)Decreased electron-phonon scattering rate
D)Enlargement of the intrinsic bandgap

💡 Explanation

Quenching introduces thermal stresses that cause greater crystalline DEFECT FORMATION. Because these defects introduce energy states within the band gap, the defect density increases, therefore option A, rather than reduced mobility from less defects introducing less electrical interference.
